Dan + Shay have already released a video version of their song "Speechless" that's all dressed up—namely, with breathtaking footage of their respective weddings playing as background. They've gone 180 degrees from that now, and have released a totally naked "Speechless" video...which consists of nothing but the title and.a stripped-down, vocals-only audio track.

In some ways it's even prettier than their wedding video. Taking the song right down to the bones—the sweetly melding vocal harmonies—puts a welcome spotlight on how lovely their voices are and how well they sing together.

Fans reacted with enthusiastic praise, and many commented that the pair should consider putting out a completely a cappella album. "I didn't know I needed this in my life," raved one commenter on YouTube. "And now I know I definitely need this."

The original version of "Speechless" is off Dan + Shay's self-titled album, which was released in June. The song was inspired by their wives, as well as that particular awe-inspiring feeling that a groom gets when first seeing his bride all dressed up in her wedding finery.

Dan + Shay are currently the road with Rascal Flatts as part of the group's Back to Us Tour. Once that tour wraps, they'll join Chris Young for the fall leg of his Losing Sleep Tour, starting in October.

At the top of 2019, Dan + Shay will head overseas for a six-date UK tour which kicks off on Jan. 17.
